Believe it or not, Kim Zolciak is the mother of six! The ‘Real Housewives of Atlanta’ star showed off her growing baby bump in this new Instagram picture over teh weekend.

The 35-year-old wrote, “Going swimming with the kiddos! The pool makes me feel so much lighter!”

Kim is preparing to welcome twins with her husband, Atlanta Falcons football star Kroy Biermann, 28. The couple have four children togheter, Brielle, 16, and Ariana, 12, whom Zolciak had from a previous marriage and Biermann adopted, and sons Kroy Jr., 2, and Kash, 1.

“I’m having twins and I couldn’t be more excited,” Zolciak told E! News in August. “I was completely shocked. I had no idea. It was a natural conception, but twins do run in the family so I guess I shouldn’t have been surprised … I can’t believe I am going to be a mom to six children. It’s going to be very busy, but it’s a dream come true.”

She confirmed she was pregnant for the fifth time on the season finale of her Bravo show, ‘Don’t Be Tardy.’ “I personally would love a little girl because Brielle’s going to be 18 soon, Ariana’s six years away from being 18,” she said. “I’ll be in a house with three boys possibly and Kroy? That’s a life of four-wheelers and football.”
